LE ROY WERTS, OF MILFORD, MISSOURI.

Specification of Letters Patent.

Patented Apr. 3, 1917.

Application filed July 17, 1916. Serial No. 109.814.

To all whom it may concern lfic it known that 1. Ln RoY WVnR'rs, a citizcn of the United States, residing at Milford, in the county of Barton and State of Missou i, have invented certain new and useful Improvements in Priming Attachments for Internal-(lo1nbustion Engines, of which the following is a specification.

This invention relates to priming attachment for automobile engines and has for its object to produce an attachment of this character which will be found especially serviceable in starting the engines of motor cars and the like, particularly in cold weather, a further object. being to produce a simple, strong, durable, cheap and ellicient attachment for the purpose named, which can be easily and economically applied to a motor car.

lVith these general objects in view, the invention consists in certain novel and peculiar features of construction and organization of parts as hereinafter described and claimed; and in order that it may be fully understood, reference is to be had to the accon'ipanying drawing, in which-- Figure 1, is a fragn'ientary plan view of a motor car equipped with an attachment embodying my invention.

Fig. 2. is an enlarged section taken on the line ll-II of Fig. 1. the gasolene priming tank being shown in elevation.

Fig. 3. is an enlarged section of the nozzle of the priming attachn'ient.

Fig. 4. is a side elevation of a modified construction of the attachment.

In the said drawing. 1 indicates the dash. 2 the engine, 3 the ca rbureter and 4 the manifold connecting the carbureter with the engine in the customary or any preferred manner. 5 is a tank or cup containing gasolenc for priming purposes. Said tank is provided with a discharge pipe 6 controlled by a valve 7. and comn'iunicating with a mixing tube the discharge pipe at its point of con'in'lunication with the tube 9 being reduccd in diameter to approximately one sixty-fourth of an inch. so that only an exceedingly fine or small drop or stream of the gasolene can pass through it into the mixing tube 8. and thus cnable the blast of air hereinafter mentioned to instantly convert such gasolcne. into vapor. The mixing tube 8 projects into the u-anil'old 4 and is secured thereto witl an air tight relation, and terminates in a nozzle 5) having small radiating jet orifices 10 for discharging a combustible mixture into the manifold, which as the engine is cranked, will be sucked into the cylinders in proper order for ignition by the customary means, not shown, to effect the operation of the engine.

11 is an air pump suitably secured to the dash I, or otherwise supported and connected at its discharge end by an air blast pipe 12 with the outer end of the mixing tube 8. 13 is" the piston of the pump and 14 the handle at the rear end of the piston stem 15, the handle being preferably accessible from the drivers seat not shown, of the car.

\Vith the construction shown, it will be apparent that preliminary to starting the engine, the operator will open valve 7 slightly, and then manipulate the pump to drive a blast of air through the mixing tube to vaporize the gasolene dropping thereinto from the pipe 6. This produces a combusti. ble mixture and such mixture is driven by the air pressure through the perforated nozzle into the manifold 4 and longitudinally thereof so that practically the entire volume of the fine wet vapor shall be taken up or absorbed by the air to insure a proper explosive mixture. and this combustible mixture is drawn into the cylinders of the engine and ignited when the engine is cranked Immediately after the engine is started the operator will cut ofi the supply of gasolene from tank 5 if he has not previously done so,

which tank is rendered inoperative until it is again needed for priming purposes. The connection for supplying fuel to the carburcter is not shown. as it forms no part of the invention.

In Fig. 4, the tank 5 is shown as secured to the dash and the handle of the valve 7 is disposed at the inner side of the dash to enable the operator to manipulate the valve conveniently from the d rivers seat. ln this case the pipe 6 is increased in length. but communicates as explained with the mixing tube 8. and the air blast 12 from the pump. likewise cou'nnunicates with said tube. The mixing tube will of course conunui'iicatc with the manifold 4. the latter. the carburctcr and the engine being omitted from Fig. l.

From the above description it will be apparent that I have produced a priming device embodying the features of advantage enumerated as dcsirablc in the statement of the object of the invention. and while I have illustrated and des ribed the preferred embodiments of the invention, it ito be understood that it is susceptible of mmlification in minor particulars without departing from the spirit and scope of the appended claim.

I claim: V I The combination with an internal combustion engine having an intake manifold, a

mixing tube having one end projecting into i the manifold and provided with fine jet orif t'lcesfacing longitudinally of the manifold, an an pump connected to the opposite end of said tube, a gasolene tank ha\'in; a pipe terminating in a hne discharge orifice 111 communication with the said tube. and a valve for controlhng said pipe.

In testimony whereof, I afiix my signature, in the presence of two witnesses.
